In the privacy of your home, you can now whiten your teeth using the Philips Zoom! Take-Home Whitening Kit. The new formula has enamel protection and a better flavor. All that is required, is an appointment with the dentist so impressions of your teeth can be taken to create two plastic trays, which are used to apply the bleaching gel on your teeth. These trays are worn according to a program designed specifically for your lifestyle. You will have a dazzling white smile in 10 to 14 days.
